Low voltage versatile telephone transmission circuit with dialler interface.

Manufacturer	Philips
Description	The TEA1067 is a bipolar integrated circuit performing all speech and line interface functions required in fully electronic telephone sets. It performs electronic switching between dialling and speech. The circuit is able to operate down to a DC line voltage of 1.6 V (with reduced performance) to facilitate the use of more telephone sets in parallel
Features	• Low DC line voltage; operates down to 1.6 V (excluding polarity guard) • Voltage regulator with adjustable static resistance • Provides supply with limited current for external circuitry • Symmetrical high-impedance inputs (64 kΩ) for dynamic, magnetic or piezoelectric microphones • Asymmetrical high-impedance input (32 kΩ) for electret microphone • DTMF signal input with confidence tone • Mute input for pulse or DTMF dialling • Power down input for pulse dial or register recall • Receiving amplifier for magnetic, dynamic or piezoelectric earpieces • Large gain setting range on microphone and earpiece amplifiers • Line current dependent line loss compensation facility for microphone and earpiece amplifiers • Gain control adaptable to exchange supply • DC line voltage adjustment capability

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large ‘Mispec’ type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’, they are however pristine, stored with us sealed in original packaging, the photographs are representative of their general condition, being of some of our actual stock, and, as with all our products they come with a full guarantee.
